# Linux kernel: Bluetooth Intel driver over-reads a buffer in error logging

The Linux kernel's Intel Bluetooth driver (btintel) printed a hardware exception string without a length bound, so it could read past the end of its 12-byte buffer. The fix limits the print to the packet length.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- unknown

## Fix

- Update the Linux kernel to a release that includes the btintel_hw_error() fix; the sources do not name a version.

## Timeline

## From the sources

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: btintel: fix buffer over-read in btintel_hw_error()

The "Exception info %s" print uses skb->data + 1, but the 12-byte
payload is not guaranteed to be NUL-terminated and can be read past
its end.

Bound the print with "%.*s" and skb->len - 1.
